Description of Cutback Bitumen MC 800
Cutback Bitumen MC 800 use is restricted to patching materials for use in cold weather Cutback MC-800 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. Cutback Bitumen MC 800 is used in the road maintenance industry where it is used as a prime coat of the base course before placing the bituminous surface course. The solvent used in the production of cutback bitumen MC-800 is typically a petroleum distillate such as kerosene, diesel fuel, or gasoline.
Cutback Bitumen MC 800 is commonly used in road construction and maintenance for various applications, including prime coating, tack coating, and surface dressing. It is applied by spraying or brushing onto the surface of the road to improve adhesion between layers of asphalt pavement or between the existing road surface and new asphalt overlays.
The solvent used in MC 800 cutback bitumen is typically a volatile petroleum distillate, such as kerosene or diesel. As the solvent evaporates, the bitumen hardens and forms a waterproof and durable layer on the road surface.
It is important to follow proper safety precautions when handling and applying cutback bitumen, as the solvents used in the mixture can be flammable and pose health risks if not handled properly. Additionally, local regulations and guidelines should be followed to ensure the safe and effective use of MC 800 cutback bitumen in road construction projects.
Application of Bitumen MC 800
Cutback Bitumen MC 800 Application is in permeable prime layers and production of adhesive or storage mixtures. Cutback asphalt used in mixing with aggregate usually contains a binding agent to help coat the surface of the aggregate. Also, cutback bitumen is ideal for primary coating and cold application due to its easy application and no need for thinning and heating.
More applications of Cutback Bitumen MC MC 800 are:
- Prime Coat: MC 800 can be used as a bonding agent, promoting adhesion between the existing road surface and the new asphalt layer, and it helps to prevent moisture infiltration.
- Tack Coat: MC 800 can be used as a tack coat between the layers When constructing multiple layers of asphalt. It ensures a strong bond between the old and new asphalt layers, reducing the likelihood of delamination and improving the overall structural integrity of the road.
- Repair: MC 800 can be used In road maintenance and used for patching and repairing damaged or deteriorated sections of asphalt roads.
- Surface Treatment: MC 800 can be used in surface treatment applications. It is sprayed onto the road surface and then covered with a layer of aggregate or chips.
Properties of Cutback MC 800
Cutback bitumen MC 800 has several properties that make it ideal for use in road construction and waterproofing applications. These properties include:
- The viscosity of bitumen MC 800 is lower than that of regular bitumen, making it easier to handle and apply.
- The medium-curing nature of cutback MC 800 makes it ideal for use in applications where a relatively quick curing time is required.
- Cutback MC 800 is highly water-resistant, making it ideal for use in roofing and waterproofing applications.
- Bitumen MC 800 has excellent adhesion properties, making it ideal for use in road construction and sealing applications.
Packing of Cutback Bitumen MC 800
The Cutback Bitumen MC 800 is usually packed in bulk, Steel Drum, and IBC Tank but The packing type depends on the quantity of the product and the specific requirements of the customer.
- 1MT IBC Tank
- 200 Kg New Steel Drum- Palletized
